Hanwha Ocean - Experts & Thought Leaders

ABS has awarded Hanwha Ocean Approval in Principle (AIP) for its Pre-FEED Standard FPSO Design intended to create an asset optimised for deployment in the deep waters of West Africa. The FPSO design is 340 m long and capable of storing approximately 2.38 million barrels of crude oil, with a daily crude oil production capacity of 190,000 barrels. Developed to accommodate topsides for crude oil and or gas production facilities, the hull is designed to operate for up to 20 years without the need for dry docking. Advanced digital solutions All kit has been electrified to reduce operational costs throughout unit’s lifecycle To address the recent tightening of environmental regulations, the FPSO is set to incorporate technologies such as zero-flaring, GHG monitoring, and an energy management system.  All equipment has been electrified to reduce operational costs throughout the unit’s lifecycle. Additionally, advanced digital solutions, including cybersecurity, digital twin, and predictive maintenance, have been integrated. Technological innovation and product development “ABS is a world pioneer in FPSO classification and we are proud to be able to use this experience to support Hanwha Ocean with their innovative, flexible approach,” said Matt Tremblay, ABS Vice President, Global Offshore. Hanwha Ocean Engineering Manager of Standard FPSO Project and Company officials of Hanwha Ocean Co., Ltd said: “We anticipate continued growth in demand for offshore plants, particularly in West Africa and South America. We will continue to strengthen our global competitiveness through continuous technological innovation and product development.”

Wärtsilä Gas Solutions, part of the technology group Wärtsilä, will supply the cargo handling systems for three new 93,000 m3 capacity Very Large Ammonia Carriers (VLACs).  The ships are being built at the Korean shipyard Hanwha Ocean Co, formerly known as DSME. Two vessels are for a Greek ship owner and one for a Japanese owner. These two orders, both booked by Wärtsilä in Q4 2024, further strengthen Wärtsilä’s position as a market-pioneering supplier of cargo handling systems. Cargo Handling System The Wärtsilä scope for the complete Cargo Handling System encompasses the engineering scope, the material scope, and the supervision, commissioning, and gas trial scope. This comprehensive system is designed to ensure optimal performance and safety in cargo handling operations. “We are happy to have Wärtsilä as a project partner for these ships. We have earlier worked with them and have complete trust in the efficiency and reliability of their products,” says Mr. Lee, Leader of the Basic Design Team, at Hanwha Ocean Co. Very Large Gas Carriers VLAC cargo tanks and hulls need to be reinforced, and the vessels will have a deeper draught VLACs are essentially Very Large Gas Carriers but designed to carry full cargoes of ammonia. Since ammonia has a high specific gravity, VLAC cargo tanks and hulls need to be reinforced, and the vessels will have a deeper draught when fully loaded. “Wärtsilä Gas Solutions has become the largest supplier of complete cargo handling systems for vessels in this segment,” comments Patrick Ha, Sales Manager, Wärtsilä Gas Solutions. Strong relationship with ship owners “We have enjoyed a long and successful relationship with Hanwha and look forward to building an even stronger relationship with ship owners through this project. We are very pleased to continue this relationship with both companies and fully committed to providing our full support throughout this latest project.” The Wärtsilä equipment is scheduled for delivery to the yard commencing in Q2 2025.

ABS has completed an industry-renowned safety evaluation of ammonia dispersion on board an ammonia-fuelled gas turbine LNG carrier design from Hanwha Ocean. ABS, in collaboration with Hanwha Ocean, conducted computational fluid dynamics simulations that modelled different ammonia release scenarios due to accidental leakages from the engine room, the pipeline and the bunkering stations on deck. The study is one of the most comprehensive in the industry, using multiple ammonia release scenarios. Further reduce risks The analyses found that the system complied with applicable ABS Rules regarding the toxicity and risks of accumulated ammonia gas. The three-dimensional, high-fidelity simulation results can also help Hanwha Ocean with improved ventilation arrangements, vent mast locations, gas release speeds and placement of air intakes for the manned spaces to further reduce risks in the detailed design stage. Application of ammonia ABS subsidiary led a quantitative risk review, helping to provide a better version ABS subsidiary, ABSG Consulting Inc., a pioneering global risk management company, conducted a quantitative risk assessment, helping to provide a better understanding of the likelihood of an incident and insight into potential threats, enabling Hanwha Ocean to design its mitigation plans accordingly. "This project allowed ABS to combine its world-pioneering modelling and simulation capability with our deep insight into the application of ammonia as a marine fuel. The toxicity of ammonia is a safety challenge and so understanding its behaviour in the event of a leak is a critical step toward enabling its wider adoption by the industry," said Patrick Ryan, ABS Senior Vice President and Chief Technology Officer. Hanwha Ocean's decarbonisation vision Patrick Ryan added: "Our analysis will help Hanwha Ocean continue to optimise its design to identify areas for enhancement and mitigate risks.”  Shon Young-chang, CTO and Head of Hanwha Ocean’s Product & Technology Strategy, said: “At Gastech 2024, we received recognition from ABS, the pioneering Classification Society, for our eco-friendly ship technologies, significantly boosting Hanwha Ocean's decarbonisation vision. We will do our utmost to ensure that shipowners can confidently choose Hanwha Ocean's products.”  ABS provides industry-renowned guidance on the application of ammonia as a marine fuel.
